Abstract

The following introduces a simplified model to concurrently represent strata deformation and steady fluid flow in a porous medium as a result of underground mining. The model is based on a coupled finite element formulation where elastic deformation controls changes in fluid hydraulic conductivity of a fractured medium idealized as a porous equivalent. Coupling is steady state and neglects the influence of seepage forces. The model is compared with a case study to reveal that changes in strata conductivity are strongly related to the intensity of the mining effect. The greatest modification of hydraulic conductivities is found to occur within the caving or severely fractured zone.
